Coquihalla Highway Closure: July 2026 Travel Advisory And Essential Traffic Updates
British Columbia’s vital mountain artery, the Coquihalla Highway (Highway 5), is facing significant disruptions as of July 24, 2026. Ministry of Transportation and Infrastructure officials have implemented temporary closures and lane diversions to accommodate urgent infrastructure resilience upgrades. Motorists traveling between Hope and Merritt are advised to anticipate delays of up to 90 minutes or utilize established detour routes through the Interior.
| Feature | Current Status & Details |
|---|---|
| Primary Route | Highway 5 (The Coquihalla) |
| Affected Segment | Hope to Merritt (Smitheram Creek Area) |
| Closure Type | Intermittent Full Closures / Single Lane Alternating |
| Current Date | July 24, 2026 |
| Reason | Climate Resiliency Paving & Bridge Inspection |
| Primary Detour | Highway 3 (Crowsnest) or Highway 1 (Fraser Canyon) |
| Estimated Reopening | Rolling openings scheduled after 8:00 PM PDT |
Context & Background
The Coquihalla Highway remains the most critical commercial and recreational link between the Lower Mainland and the rest of Western Canada. Following the transformative reconstruction projects that took place between 2021 and 2025, the 2026 summer season marks a transition into long-term preventative maintenance. These July 2026 closures are part of the "Future-Proofing BC Highlands" initiative, aimed at ensuring the corridor can withstand the increasing frequency of extreme weather events.
Current operations are centered near the Zopkios Brake Check and the Great Bear Snowshed. Engineers are performing deep-layer pavement reinforcement and installing advanced sensor arrays designed to monitor slope stability in real-time. While these upgrades are essential for winter readiness, the mid-summer timing coincides with peak tourism traffic, creating a bottleneck for those heading to the Okanagan Valley.
Historically, the Coquihalla has been prone to sudden closures due to its high-altitude environment. However, the current July 24 restrictions are planned interventions rather than emergency responses to accidents. The Ministry has emphasized that performing these high-intensity upgrades during the dry summer window is necessary to avoid more intrusive closures during the volatile autumn rain season.
Impact & Utility
The closure significantly impacts logistics, tourism, and local commuting. With Highway 5 restricted, traffic volume on Highway 3 (Crowsnest) and Highway 1 (Fraser Canyon) has increased by an estimated 40%. Travelers should be aware of the following operational impacts:
- Commercial Transport: Heavy-duty trucks are being prioritized during specific "windowed" openings to maintain the supply chain. Carriers should check the DriveBC portal for specific weight and width restrictions currently in effect near the Box Canyon segment.
- Transit Times: The traditional two-hour trip from Hope to Merritt is currently taking upwards of three and a half hours. If using Highway 3, expect steep grades and winding turns that are not suitable for high-speed travel.
- Fuel and Services: Services at Britton Creek remain open, but congestion at the pumps is high. Drivers are encouraged to fuel up in Hope or Merritt before entering the mountain pass.
- Emergency Access: Emergency vehicles retain priority access through the construction zones via dedicated bypass lanes.
For those traveling with livestock or perishable goods, the Fraser Canyon (Highway 1) is the recommended alternative, despite the added distance. It offers more consistent grades and fewer stop-start cycles compared to the congested mountain pass sections of the Coquihalla during this July 2026 maintenance window.

What's Next
The Ministry of Transportation expects the current phase of the Smitheram Creek project to conclude by the end of this week. However, motorists should prepare for "night-only" closures beginning July 27, 2026, as crews shift to line painting and the installation of reflective overhead gantry systems. These systems are part of a 2026 pilot program to improve visibility during the heavy fog frequently encountered at the Coquihalla Summit.
Long-term, the BC Highway Administration is looking toward a fully digital traffic management system for the Coquihalla by late 2027. This will include automated lane control signals to manage traffic flow during future maintenance without requiring full highway shutdowns.
For the remainder of this weekend, the following schedule is anticipated:
- July 24-25: Intermittent 20-minute stoppages during daylight hours.
- July 26: Full reopening of northbound lanes by noon to accommodate return traffic.
- August 2026: Minor shoulder work with no expected impact on travel times.
Stay tuned to local radio frequencies and the official DriveBC digital maps for minute-by-minute updates. Safety remains the priority, and drivers are reminded to obey all posted speed limits in construction zones, as fines are doubled when workers are present.
